Figure 3From: Nicotine exposure during differentiation causes inhibition of N-myc expressionDifferentiated nhpESC do not express OCT4. Cells were stained by immunofluorescence for the pluripotency marker OCT4. A: NHP primary lung fibroblasts served as negative controls for OCT4; B: undifferentiated nhpESC 4706 served as positive controls for OCT4; C: nhpESC 4706 differentiated into fibroblasts were negative for OCT4, similar to panel A primary lung fibroblasts.Back to article page
